Abstract
During the last few years, a number of Receive Antenna Shift Keying (RASK) schemes have been proposed. RASK has low detection complexity since only one receive antenna is activated to transmit spatial bits. Space-Time Block Code (STBC) offers an excellent way to exploit the high-rate of Multiple-Input Multiple-Output (MIMO) systems, and enjoys the implementation simplicity and low decoding complexity. In this paper, a novel transmission scheme, called Space-Time Block Coded Generalised Receive Spatial Modulation (STBC-GRSM) is proposed to take benefits from both STBC and GRSM schemes. Furthermore, a simple tight upper-bound of the Average Bit Error Probability (ABEP) of the proposed system is also provided. Finally, simulation results are shown to be in agreement with our ABEP bound and they illustrate the significant performance gains that can be obtained with our STBC-GRSM scheme compared to STBC, GRSM and Space-Time Block Coded Spatial Modulation (STBC-SM).
